git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "The most significant change here is the extension of the Energy Model to cover non-CPU devices (as well as CPUs) from Lukasz Luba. There is also some new hardware support (Ice Lake server idle states table for intel_idle, Sapphire Rapids and Power Limit 4 support in the RAPL driver), some new functionality in the existing drivers (eg. a new switch to disable/enable CPU energy-efficiency optimizations in intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci, devfreq), including the elimination of W=1 build warnings from cpufreq done by Lee Jones. Specifics: - Make the Energy Model cover non-CPU devices (Lukasz Luba). - Add Ice Lake server idle states table to the intel_idle driver and eliminate a redundant static variable from it (Chen Yu, Rafael Wysocki). - Eliminate all W=1 build warnings from cpufreq (Lee Jones). - Add support for Sapphire Rapids and for Power Limit 4 to the Intel RAPL power capping driver (Sumeet Pawnikar, Zhang Rui). - Fix function name in kerneldoc comments in the idle_inject power capping driver (Yangtao Li). - Fix locking issues with cpufreq governors and drop a redundant "weak" function definition from cpufreq (Viresh Kumar). - Rearrange cpufreq to register non-modular governors at the core_initcall level and allow the default cpufreq governor to be specified in the kernel command line (Quentin Perret). - Extend, fix and clean up the intel_pstate driver (Srinivas Pandruvada, Rafael Wysocki): * Add a new sysfs attribute for disabling/enabling CPU energy-efficiency optimizations in the processor. * Make the driver avoid enabling HWP if EPP is not supported. * Allow the driver to handle numeric EPP values in the sysfs interface and fix the setting of EPP via sysfs in the active mode. * Eliminate a static checker warning and clean up a kerneldoc comment. - Clean up some variable declarations in the powernv cpufreq driver (Wei Yongjun). - Fix up the ->enter_s2idle callback definition to cover the case when it points to the same function as ->idle correctly (Neal Liu). - Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson). - Make the PM core emit "changed" uevent when adding/removing the "wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi). - Add a helper macro for declaring PM callbacks and use it in the MMC jz4740 driver (Paul Cercueil). - Fix white space in some places in the hibernate code and make the system-wide PM code use "const char *" where appropriate (Xiang Chen, Alexey Dobriyan). - Add one more "unsafe" helper macro to the freezer to cover the NFS use case (He Zhe). - Change the language in the generic PM domains framework to use parent/child terminology and clean up a typo and some comment fromatting in that code (Kees Cook, Geert Uytterhoeven). - Update the operating performance points OPP framework (Lukasz Luba, Andrew-sh.Cheng, Valdis Kletnieks): * Refactor dev_pm_opp_of_register_em() and update related drivers. * Add a missing function export. * Allow disabled OPPs in dev_pm_opp_get_freq(). - Update devfreq core and drivers (Chanwoo Choi, Lukasz Luba, Enric Balletbo i Serra, Dmitry Osipenko, Kieran Bingham, Marc Zyngier): * Add support for delayed timers to the devfreq core and make the Samsung exynos5422-dmc driver use it. * Unify sysfs interface to use "df-" as a prefix in instance names consistently. * Fix devfreq_summary debugfs node indentation. * Add the rockchip,pmu phandle to the rk3399_dmc driver DT bindings. * List Dmitry Osipenko as the Tegra devfreq driver maintainer. * Fix typos in the core devfreq code. - Update the pm-graph utility to version 5.7 including a number of fixes related to suspend-to-idle (Todd Brandt). - Fix coccicheck errors and warnings in the cpupower utility (Shuah Khan). - Replace HTTP links with HTTPs ones in multiple places (Alexander A.

2020-07-30memory: samsung: exynos5422-dmc: Add module param to control IRQ modeLukasz Luba1-2/+7
The driver can operate in two modes relaying on devfreq monitoring mechanism which periodically checks the device status or it can use interrupts when they are provided by loaded Device Tree. The newly introduced module parameter can be used to choose between devfreq monitoring and internal interrupts without modifying the Device Tree. It also sets devfreq monitoring as default when the parameter is not set (also the case for default when the driver is not built as a module).

2020-07-24memory: samsung: exynos5422-dmc: Do not ignore return code of regmap_read()Krzysztof Kozlowski1-3/+9
Check for regmap_read() return code before using the read value in following write in exynos5_switch_timing_regs(). Pass reading error code to the callers. This does not introduce proper error handling for such failed reads (and obviously regmap_write() error is still ignored) because the driver ignored this in all places. Therefor it only fixes reported issue while matching current driver coding style: drivers/memory/samsung/exynos5422-dmc.c: In function 'exynos5_switch_timing_regs': >> drivers/memory/samsung/exynos5422-dmc.c:216:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
2020-07-15memory: tegra: Add Tegra132 compatible string matchThierry Reding1-0/+1
Ensure that the driver will bind against the Tegra132 instantiation of the external memory controller. While the two are roughly the same from a capability perspective, they do require some incompatible changes to the programming sequences and therefore need separate compatible strings.

2020-07-14memory: tegra: Fix KCONFIG variables for Tegra186 and Tegra194Jon Hunter1-2/+2
Commit a127e690b051 ("memory: tegra: Add support for the Tegra194 memory controller") and commit 4e04b88633ae ("memory: tegra: Only include support for enabled SoCs") incorrectly added the KCONFIG variables CONFIG_ARCH_TEGRA186_SOC and CONFIG_ARCH_TEGRA194_SOC to the Tegra EMC driver. These KCONFIG variables do not exist and prevent the EMC driver from being probed on Tegra186 and Tegra194. These KCONFIG variable names are simply missing one underscore and so fix this by adding the necessary underscore to the variable names.
